In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. Configuration FIG. 1 shows an example of a functional block diagram of the game apparatus of the present embodiment. In this figure, the present embodiment only needs to include at least the processing unit 100 (or include the processing unit 100 and the storage unit 170), and the other units (functional blocks) may be optional components. it can.

  The operation unit 160 is used by the player to input operation data, and functions thereof are hardware such as a lever, button, steering, shift lever, accelerator pedal, brake pedal, microphone, sensor, touch panel, or chassis. realizable.

  The storage unit 170 serves as a work area such as the processing unit 100 or the communication unit 196, and its function can be realized by hardware such as a RAM.

  An information storage medium 180 (a computer-readable medium) stores programs, data, and the like, and functions as an optical disk (CD, DVD, Blu-ray disk), magneto-optical disk (MO), magnetic disk, and hard disk. It can be realized by hardware such as a magnetic tape or a memory (ROM). The processing unit 100 performs various processes of this embodiment based on a program (data) stored in the information storage medium 180. That is, the information storage medium 180 stores (records and stores) a program for causing the computer to function as each unit (each unit) of the present embodiment (a program for causing the computer to implement each unit).

  The display unit 190 outputs an image generated according to the present embodiment, and the function thereof can be realized by hardware such as a CRT, LCD, or HMD (head mounted display). Here, one display may be provided, or two displays may be provided.

  Further, a touch panel display may be used as the display unit 190 so that the player can function as an operation unit that performs operation input. In the case of having two displays, one of the displays may be configured as a touch panel display.

  The sound output unit 192 outputs the sound generated by the present embodiment, and its function can be realized by hardware such as a speaker or headphones.

  The portable information storage device 194 stores player personal data, game save data, and the like. As the portable information storage device 194, a memory card or the like can be considered.

  The communication unit 196 performs various controls for communicating with the server, and the function can be realized by hardware such as various processors or communication ASICs, a program, or the like.

  A program (data) for causing a computer to function as each unit of the present embodiment may be distributed from the information storage medium of the server to the information storage medium 180 (storage unit 170) via the network and communication unit 196. Good. Use of such server information storage media is also within the scope of the present invention.

  The processing unit 100 (processor) performs various processes such as a game process, an image generation process, and a sound generation process based on operation data from the operation unit 160, a program, and the like. In this case, the processing unit 100 performs various processes using the storage unit 170 as a work area. The function of the processing unit 100 can be realized by hardware such as various processors (main processor, drawing processor, DSP, etc.) or ASIC (gate array, etc.), and a program (game program).

  The processing unit 100 includes a character control unit 110, a display control unit 114, a parameter control unit 116, an image generation unit 130, and a sound generation unit 140.

  The character control unit 110 performs processing for controlling the player character, the teammate character, and the enemy character in the game field based on the input information. The character control unit 110 includes a cooperative play control unit 112. The cooperative play control unit 112 shifts to the cooperative play mode when the predetermined cooperative play mode start condition is satisfied, and in the cooperative play mode, the enemy character moves in a predetermined direction by the attack of the player character, and by the attack of the teammate character. A cooperative attack in which the enemy character moves in the direction of the player character is controlled.

  The player character to be operated is an object that moves based on operation input information from the player. Further, a teammate character that is a non-operation target is not an object that moves directly based on operation input information from a player, but an object that is controlled by a computer. The enemy character is an object controlled by the computer in the single player mode, and is an object in which the opponent player moves and moves based on the operation input information in the multiplayer mode.

  Whether or not the cooperative play mode start condition is satisfied may be determined based on at least one of the parameters of any character, the success or failure of the attack, and the input of the player.

  Whether or not the cooperative play mode end condition is satisfied may be determined based on the success or failure of the cooperative attack. Until the cooperative play mode ends, control may be performed so that the cooperative attack can be performed a plurality of times or many times.

  The cooperative attack is an attack performed based on an operation input by the player, in which the player character and the teammate character cooperate in some form to attack the enemy character.

  The cooperative play control unit 112 receives timing input during the cooperative play mode, determines success / failure of the timing input based on at least one of the position and distance of the player character and the enemy character, and cooperated play mode based on the success / failure of the timing input. An end condition may be determined.

  The timing input is an input of a type in which the success or failure of the input is determined by the input timing, or an input of a type in which the success or failure of the input is determined by the parameter value at the input timing. Based on at least one of the positions and distances of the player character and the enemy character, an input success period may be set as the input timing OK, and it may be determined that the timing input is successful when there is a timing input within the input success period. The success or failure of the timing input may be determined based on at least one of the position and distance between the player character and the enemy character at the time of timing input.

  The cooperative play mode end condition may be set, for example, when the timing input fails or when the timing input failure continues a predetermined number of times.

  The cooperative play control unit 112 receives a timing input during the cooperative play mode, determines the success or failure of the timing input based on at least one of the position and distance of the player character and the enemy character, and performs a cooperative attack based on the success or failure of the timing input. Success or failure may be determined.

  The timing input for determining the success or failure of the cooperative attack and the timing input for determining the cooperative play mode end condition may be performed separately, or the same may be used for both.

  Depending on the success or failure of the cooperative attack, the score or the magnitude of damage to the enemy character may be changed. Moreover, you may change the parameter of each character by the success or failure of a cooperation attack.

  The display control unit controls display of various indicators such as gauges, and instructs the input timing of the timing input by changing the relative positional relationship between the instruction mark and the reference position during the cooperative play mode. It functions as a display control unit for timing input.

  The display control unit 114 may change the relative positional relationship between the instruction mark and the reference position based on at least one of the position and distance of the player character and the enemy character.

  For example, an enemy character may be knocked off by an attack and moved in the virtual space.

  For example, the input timing may be notified when the instruction mark approaches the stationary reference position, or may be notified when both the reference position and the instruction mark move and the distance changes. . For example, when the position of the player character is fixed and the enemy character moves, display control is performed so that the instruction mark corresponding to the position of the enemy character approaches the reference position corresponding to the position of the player character. May be.

  In this way, the movement of the enemy character in the virtual three-dimensional space can be linked to the change in the relative positional relationship between the instruction mark that indicates the input timing and the reference position.

  The cooperative play control unit 112 may perform control to change the moving speed of the enemy character based on the number of cooperative attacks performed during the cooperative play mode.

The number of cooperative attacks may be the number of continuous attacks, the number of successes, or the number of continuous successes.
For example, the enemy character may be controlled to move faster as the number of cooperative attacks increases. When determining the success or failure of timing input based on at least one of the position and distance of the player character and enemy character, the timing input becomes difficult as the enemy character's moving speed increases. The degree can be increased.

  The cooperative play control unit 112 may perform control to change the difficulty level of the timing input determination performed during the cooperative play mode based on a predetermined parameter.

  The predetermined parameter may be, for example, a parameter indicating the degree of cooperation or closeness between the player character and the teammate character.

  The cooperative play control unit 112 may determine the end condition of the cooperative play mode based on the success / failure of the timing input performed during the cooperative play mode or the number of consecutive success / failures.

  When the enemy play is defeated during the cooperative play mode, the cooperative play control unit 112 may perform at least one of a process of performing a special addition to the game result and a process of performing a special image effect.

  The parameter control unit performs increase / decrease control of various parameters, and functions as a special technique potential parameter increase / decrease control unit that increases / decreases the value of the special technique potential parameter based on the attack status of the player character.

  The cooperative play control unit 112 displays a special technique potential parameter display image for notifying the value of the special technique potential parameter during the cooperative play mode, determines whether or not the special technique potential parameter has reached a predetermined level, If the player character is put into a special technique usable state and the player character is in the special technique usable state, and if a special technique input for instructing the use of the special technique is accepted. Controls the player character to perform an attack using a special technique under a predetermined condition, and the parameter control unit 116 decreases the special technique potential parameter when the player character performs an attack using the special technique. It may be.

  The player can determine whether or not the special technique can be used from the special technique potential parameter display image. If an attack using a special technique is performed, the special technique potential parameter will decrease, so even if the special technique is used, the normal cooperative attack and the special technique can be used selectively, and whether or not the special technique is used. It may be left to the player's judgment. For example, a button for a special technique and a button for a normal cooperative attack may be separately provided so that any one can be selected and used in a special technique usable state.

  The cooperative play control unit 112 may request an input instructing start as a predetermined cooperative play mode start condition, and may shift to the cooperative play mode when there is an input instructing start corresponding to the request.

  The cooperative play control unit 112 may set the enemy character in an attack impossible state or an input control impossible state during the cooperative play mode. The attack impossible state is a state in which the enemy character cannot attack the player character by control from the computer or the opponent's character. The enemy character may or may not be able to avoid an attack from the player character by control from the computer or the opponent's character.

  The input uncontrollable state is a state in which the attacking action and moving action of the enemy character cannot be controlled by control from the computer or the opponent's character. The enemy character cannot attack the player character. is there.

  The image generation unit 130 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100 and outputs the drawing processing to the display unit 190. In this case, the image generated by the image generation unit 130 may be a so-called three-dimensional image.

  When a so-called three-dimensional game image is generated, first, vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex defining a display object (object, model) is included. Display object data (object data, model data) is input, and vertex processing is performed based on vertex data included in the input display object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary. In vertex processing, geometry processing such as vertex movement processing, coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, perspective transformation, or light source processing is performed, and the display object is configured based on the processing result. The given vertex data is changed (updated, adjusted) for the vertex group. Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (fragment processing) for drawing pixels constituting an image (fragments constituting a display screen) is performed. In pixel processing, various processes such as texture reading (texture mapping), color data setting / changing, translucent composition, anti-aliasing, etc. are performed to determine the final drawing color of the pixels that make up the image, and perspective transformation is performed. The drawing color of the object is output (drawn) to the drawing buffer 174 (buffer that can store image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) set in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  It should be noted that the vertex processing and pixel processing performed by the image generation unit 130 are performed by hardware that can program polygon (primitive) drawing processing by a shader program described in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). It may be realized. Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of rendering processing is high, and the expressive power can be greatly improved compared to fixed rendering processing by hardware. .

  The image generation unit 130 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing the display object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the display object. Then, display object data after geometric processing (after perspective projection conversion) (position coordinates of vertex of the display object, texture coordinates, color data (luminance data), normal vector, α value, etc.) is stored in the main storage unit 172. Saved.

  Texture mapping is a process for mapping a texture (texel value) stored in the storage unit 170 to a display object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the storage unit 170 using texture coordinates or the like set (given) at the vertex of the display object. Then, a texture that is a two-dimensional image is mapped to a display object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing can be performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which Z values (depth information) of drawing pixels are stored. . That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer is referred to. Then, the Z value of the referenced Z buffer is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is a Z value (for example, a small Z value) on the near side when viewed from the virtual camera. In some cases, the drawing process of the drawing pixel is performed and the Z value of the Z buffer is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value). For example, in normal α blending, a process for obtaining a color obtained by combining two colors by performing linear interpolation with the α value as the strength of synthesis is performed.

  The α value is information that can be stored in association with each pixel (texel, dot), and is, for example, plus alpha information other than color information indicating the luminance of each RGB color component. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The sound generation unit 140 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the game system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play.

2. Next, an embodiment to which the present invention is applied will be described in detail. In this embodiment, a character object that moves / moves in response to a player's operation input is a player character, and an object that is controlled by a computer and plays cooperatively with the player character is an ally character, and is controlled by the computer or operated by an opponent in a multiplayer game. The object controlled by the input is the enemy character.

  FIG. 2 is an example of the game image of the present embodiment, and is a game image in a state that is not the cooperative play mode (referred to as a normal mode).

  The player character 210 and the enemy character 220 play a battle in a virtual three-dimensional space. A teammate character (not shown in FIG. 2) can move following the player character 210 and attacks the enemy character 220 in cooperation with the player character 210 under a predetermined condition (cooperative play mode). be able to.

  Reference numerals 222 and 224 respectively denote a first parameter gauge (for example, a physical strength gauge) and a second parameter gauge (for example, a break gauge) of the enemy character 220. The first parameter gauge 222 of the enemy character 220 is displayed based on a first parameter (for example, a physical strength parameter) set in relation to the enemy character. The first parameter is a parameter that decreases according to the damage received by each character, and is basically a parameter that does not increase until it is reset once it is reduced. The system controls the character to disappear when the parameter reaches a predetermined value (for example, 0).

  The second parameter gauge (for example, break gauge) 222 of the enemy character 220 is displayed based on the second parameter (for example, break parameter) set in relation to the enemy character 220. The second parameter is a parameter that decreases according to the damage received by each character but recovers over time. In this embodiment, even if an enemy is attacked against a dark cloud, much damage is not given. When the enemy character 220 is put into a break state in which the second parameter gauge is 0, it is possible to shift to the cooperative play mode and use the special move.

  Reference numerals 212 and 214 denote a first parameter gauge and a second parameter gauge of the player character 210, respectively, which may be displayed in association with the mark 216 of the player character 210. The first parameter gauge 212 of the player character 210 is displayed based on the first parameter set in relation to the player character 210. The second parameter gauge 214 of the player character 210 is displayed based on the second parameter set in relation to the player character 210.

  Reference numerals 232 and 234 respectively denote a first parameter gauge and a second parameter gauge of an ally character (not shown in FIG. 2, 230 in FIG. 3), and are displayed in association with the mark 236 of the ally character 230. May be. The first parameter gauge 232 of the teammate character 230 is displayed based on the first parameter set in relation to the teammate character 230. The second parameter gauge 234 of the teammate character 230 is displayed based on the second parameter set in relation to the teammate character 230.

  FIG. 8 is an example of a game image of the present embodiment, and is a game image showing a state where the enemy character 220 is floating in a break state.

  In the present embodiment, when the predetermined cooperative play mode start condition is satisfied, the cooperative play mode is entered.

  As a case where the predetermined cooperative play mode start condition is satisfied, for example, the following case may be used. When the player character 210 attacks the enemy character 220 in a state where the second parameter gauge 224 of the enemy character 220 is 0 (state where the second parameter is 0), the enemy character 220 is in a predetermined state (here, floating). In other words, when the player makes an input indicating acceptance of the “cooperative play” invitation, the mode changes from the normal mode to the cooperative play mode. May be.

  Whether or not the teammate character 230 invites cooperative play may be determined according to the position of the teammate character 230 when the enemy character 220 is in a predetermined state. For example, when the enemy character 220 is in a predetermined state and the teammate character 230 is far from the enemy character 220 by a predetermined distance or more, the teammate character 230 may not invite the cooperative play.

  The current mode may be managed by a mode flag or the like. In the present embodiment, the gauge displayed and the possible attacks differ depending on the mode.

  FIG. 3 is an example of the game image of the present embodiment, and is a game image in the cooperative play mode.

  When the cooperative play mode is entered, the teammate character 230 instantaneously moves near the enemy character 220 floating in the air.

  During the cooperative play mode, until the cooperative play mode end condition is satisfied, the cooperative attack control for causing the player character 210 and the teammate character 230 to attack the enemy character 220 is performed based on the input information. As the cooperative attack, the enemy character 220 moves in a predetermined direction by the attack of the player character 210, and the enemy character 220 moves in the direction of the player character 210 by the attack of the teammate character 230.

  Here, the attack on the enemy character 220 of the player character 210 and the ally character 230 may be set as a cooperative attack, or the attack on the enemy character 220 of the player character 210 and the attack on the enemy character 220 of the ally character 230 may be separately considered. It may be a cooperative attack.

  During the cooperative play mode, the enemy character 220 may be set in a non-attackable state or incapable of input control (computer controlled state).

  The cooperative attack is performed by timing input when the player presses a predetermined button (referred to as a first button), and the success or failure of the timing input is determined based on at least one of the position and distance of the player character 210 and the enemy character 220. .

  In this embodiment, in order to instruct the input timing of the timing input, the timing gauge 240 is displayed on the screen in the cooperative play mode, and the icon 226 and the instruction mark 242 indicating the enemy character 220 are close to the reference position 244. Display control is performed. Specifically, display control is performed in which an icon 226 indicating an enemy character 220 and an instruction mark 242 flow from the right side of the timing gauge 240 toward the reference position.

  The icon 226 indicating the enemy character 220 is moved along with the instruction mark 242. In this way, it is possible to perform an effect that emphasizes that the approach of the instruction mark 242 is the approach of the enemy character 220.

  When a predetermined button (first button) is pressed at a timing when the icon 226 indicating the enemy character 220 and the instruction mark 242 pass the reference position 244, the timing OK is determined. The timing input determination may have a certain range, and the timing OK determination may be performed when the timing input is performed when the instruction mark 242 is in one of the permitted ranges 246.

  5A and 5B are diagrams for explaining the permitted range of the timing gauge.

  As shown in FIG. 5A, the permission range 246 is divided into a reference position 244, a first permission range 247-1, 247-2, and a second permission range 248-1, 248-2. When the timing is input at the timing when the instruction mark 242 overlaps the reference position 244, the highest score is given or the enemy character is greatly damaged. Since the first permission ranges 247-1 and 247-2 are closer to the reference position 244 than the second permission ranges 248-1 and 248-2, the first permission ranges 247-1 and 247-2 When the timing input is made at the overlapping timing, a higher score is given compared to the case where the timing input is made at the timing overlapping the second permission ranges 248-1 and 248-2, or to the enemy character You may comprise so that a big damage may be given.

  If the timing input is successful, control is performed in which the enemy character 220 is struck in the direction of the teammate character 230 by moving the player character 210 or an item held by the player character 210 (moving the enemy character 220 in the virtual space). . The hit enemy character 220 is returned by the teammate character 230 and flies back toward the player character 210, so that the player again performs timing input in order to return the enemy character 220 that has flew away.

  During the cooperative play mode, the enemy character 220 receives damage when attacked by the player character 210 and further receives damage when attacked by the teammate character 230.

  During this time, the enemy character 220 becomes unable to attack, and a cooperative attack in which the player character 210 and the teammate character 230 cooperate to strike the enemy character 220 is possible. Although the cooperative attack can be applied to the enemy character 220 any number of times during the cooperative play mode, the cooperative play mode ends when the player fails to input the timing.

  If the timing input fails and the cooperative play mode ends, the enemy character 220 that has moved toward the player character 210 and the player character 210 collide, and the player character 210 may fall or be damaged. Good. In this way, the cooperative play mode is not a mode that merely benefits the player, but a mode that may be disadvantaged when it fails, and when the player chooses to enter the cooperative play mode. In addition, a game is created in which profits and disadvantages are weighed.

  During the cooperative play mode, the teammate character 230 always succeeds in attacking. Therefore, during the cooperative play mode, if the enemy character 220 is damaged by the attack of the player character 210 and the remaining physical strength parameter of the enemy character 220 decreases to a value that becomes 0 by the attack of the next ally character 230, the next The enemy character 220 may disappear at that time without performing the attacking action of the teammate character 230. When the enemy character is defeated during the cooperative play mode, a process for performing special addition to the game result, a process for generating a special item, or a special image effect is performed.

  FIG. 4 is a game image in the cooperative play mode. The game image in FIG. 4 is a game image several frames after the game image in FIG. 3, and the enemy character 220 is closer to the player character 210 in the virtual space (the distance between the player character 210 and the enemy character 220). Is a game image in a state where is shorter.

  In the present embodiment, the instruction mark 242 on the timing gauge 240 moves in conjunction with the movement of the enemy character 220 in the virtual space.

  FIGS. 12A and 12B are conceptual diagrams for explaining processing for interlocking movement of the instruction mark 242 of the timing gauge 240 and the enemy character 220.

  In the present embodiment, the player character 210 and the teammate character 230 perform a cooperative attack that strikes the enemy character 220, whereby the enemy character 220 is moved back and forth between the player character 210 and the teammate character 230. become.

  FIG. 12A shows the positional relationship between the character in the virtual space at time t1 and the positional relationship between the indication marks of the parameter gauge, and FIG. 12B shows the positional relationship between the character in the virtual space at time t2 and the parameters. This shows the positional relationship of the gauge indication marks.

  PK and MK indicate the positions of the player character 210 and the teammate character 230 in the virtual three-dimensional space, respectively. During the cooperative attack, the enemy character 220 moves back and forth on a straight line connecting PK and MK.

K is the distance between the player character 210 and the teammate character 230 in the virtual three-dimensional space. Assuming that the distance between the player character 210 and the teammate character 230 is fixed during a cooperative attack, K is calculated from the PK coordinates (x _PK , y _PK , z _PK ) and the MK coordinates (x _MK , y _MK , z _MK ). Can be sought.

TK-t1 indicates the position of the enemy character 220 at time t1. L1 is the distance between the player character 210 and the enemy character 220 at time t1. L1 can be obtained from the coordinates ( _xPK , _yPK , _zPK ) of _PK and the coordinates ( _xMK-t1 , _yMK-t1 , _zMK-t1 ) of MK-t1 at time t1.

  Further, k is the length of the parameter gauge 240 (length from the reference position 244), and the point m-t1 indicates the position of the indication mark at time t1. l1 indicates the distance from the reference position to the point m-t1 at time t1.

  At time t1, display control may be performed such that the instruction mark 242 is arranged at a point m−t1 such that K: L1 = k: l1.

TK-t2 indicates the position of the enemy character 220 at time t2. L2 is the distance between the player character 210 and the enemy character 220 at time t2. L2 can be obtained from the coordinates ( _xPK , _yPK , _zPK ) of _PK and the coordinates ( _xMK-t2 , _yMK-t2 , _zMK-t2 ) of MK-t2 at time t2.

  Point m-t2 indicates the position of the instruction mark at time t2. l2 indicates the distance from the reference position to the point m−t2 at time t2.

  At time t2, display control may be performed such that the instruction mark 242 is arranged at a point m−t2 such that K: L1 = k: l2.

  In this way, by controlling the position of the moving instruction mark 242 based on at least one of the position and distance of the player character 210 and enemy character 220 in the virtual space, at least the position and distance of the player character 210 and enemy character 220 are controlled. The success or failure of the input timing of the timing input can be determined based on one.

  Further, it may be controlled so that the moving speed of the struck enemy character 220 increases as the number of consecutive cooperative attacks increases. In this way, the movement speed of the instruction mark 242 that moves in conjunction with the position and movement speed of the enemy character 220 also increases, so the difficulty of timing input also increases. Therefore, as the number of consecutive cooperative attacks increases, the difficulty of timing input for hitting enemy characters increases, and it becomes difficult to maintain the cooperative play mode.

  Further, control may be performed so as to change the difficulty level of timing input according to the value of a predetermined parameter. FIG. 5B shows a state of the permission range 246 ′ when the difficulty level is lowered as compared with the case of FIG. In this way, the difficulty level of timing input may be realized by changing the width of the permitted range. In this way, the input period of the timing input is extended, and it becomes difficult to make mistakes. Therefore, the difficulty of timing input can be reduced.

  Note that a parameter value indicating the familiarity between the player character 210 and the teammate character 230 may be used as the predetermined parameter. In this way, the difficulty level of timing input during cooperative play can be changed according to the familiarity between the player character 210 and the teammate character 230.

  FIG. 6 is a game image in the cooperative play mode, and is a diagram for explaining a special technique.

  The Special Move cannot be used in the normal mode, and can be used when the third parameter reaches a predetermined level in the cooperative play mode. The third parameter is a parameter that increases according to the damage given to the enemy character 220 and decreases when the player character 210 uses the special technique.

  During the cooperative play mode, a third parameter gauge (for example, a deadly technique potential gauge) 250 is displayed. The third parameter gauge 250 is displayed on the basis of a third parameter (for example, a potential parameter for the special technique) set in relation to the player character 210. In the present embodiment, when the third parameter reaches a predetermined level (in this case, MAX252), it is possible to use a special move.

  The player can determine whether or not the third parameter has reached a predetermined level using the third parameter gauge 250. As shown in FIG. 6, when the third parameter gauge 250 reaches the MAX position 252, it indicates that the special technique can be used. The player can use the special technique at a desired timing when the special technique becomes available.

  By using the button for the special technique (referred to as the second button) in the timing input of the cooperative attack performed in the cooperative play mode state, the special technique can be used. When the special technique can be used, an icon 260 indicating that the second button can be used near the icon 216 indicating the player character 210 of the timing gauge 240 (the special technique can be used), An icon 262 indicating that the button is usable (a normal cooperative attack is usable) is displayed. Therefore, the player performs timing input using any of the buttons.

  If you want to use a special move, use the second button to enter timing. The success / failure of using the special technique is determined by timing determination of timing input. Similar to the timing determination in the case of a normal cooperative attack, if timing input is performed at a timing when the instruction mark 226 is within the permitted range 246, it is determined that the timing is OK.

  If it is determined that the timing is OK, the special move is executed. When the Special Move is executed, the third parameter decreases. Further, when the special technique is executed, at least one of addition of a special score (including addition of special damage to the enemy character) and special image effect is performed.

  In the present embodiment, the content of the additional effect of the special technique is also determined by determining the input timing of the player.

  FIG. 7 is a diagram illustrating a timing determination roulette for an additional effect of a special move.

  When the timing determination of the timing input of the second input button instructing the use of the special move is OK, the instruction bar 382 displayed on the timing determination roulette 380 rotates. The player inputs a timing for receiving an additional effect. When a timing is input at a timing when the instruction bar 382 is within the additional effect applying area, an additional effect is applied. Depending on whether or not the timing of additional effect determination is successful, the addition of a special score (including the provision of special damage to enemy characters) and the presence / absence of a special image effect may be determined, or the content to be applied is determined. You may do it. Further, when the timing input for determining the additional effect is successful, additional special points may be added (including the addition of special damage to the enemy character), and further special image effects and items may be added.

  The difficulty level of the input effect timing determination input may be changed according to a predetermined parameter value (for example, a parameter value indicating the familiarity between the player character 210 and the teammate character 230). If it does in this way, according to the familiarity of the player character 210 and the friend character 230, the effect at the time of using a special technique can be changed.

3. Process of this Embodiment FIG. 9 is a flowchart for explaining the flow of the transition process from the normal mode to the cooperative play mode of this embodiment.

  When the game is started or when the cooperative play mode is shifted to the normal mode (B), the following processing is performed to determine whether or not the shift to the cooperative play mode is performed. The following processing may be performed for each frame, or when there is a series of motion processing or animation processing over a plurality of frames, it may be performed at the breaks.

  It is determined whether or not the first parameter (for example, the physical strength parameter) of the enemy character is a value that means annihilation.

  If the value does not mean extinction, input in the normal play mode is accepted, and character control processing corresponding to the input is performed (step S20). For example, the player character accepts an input such as an attack input of the player character against the enemy character in the normal input mode or a movement input of the player character, and performs a character control process corresponding to the input.

  It is determined whether or not the value of the second parameter (for example, break parameter) of the enemy character is 0. If it is not 0, the shift to the cooperative play mode is not performed (in the case of N in step S30). If it is 0 (Y in Step S30), it is determined whether or not the player character has successfully attacked the enemy character. If the attack has failed (N in Step S40), the cooperative play mode is entered. Will not be transferred.

  If the attack is successful (Y in step S40), the enemy character is set in a predetermined state (for example, suspended in the air), and an invitation effect of cooperative play from the teammate character to the player character is performed. Waits for a response input from (step S50).

  It is determined whether or not there is a response input within a predetermined period. If there is no response input (N in step S60), the shift to the cooperative play mode is not performed. If there is a response input (in the case of Y in step S60), it is determined whether or not it is a response to accept the invitation for cooperative play. If it is not a response of acceptance (in the case of N in step S70), cooperative play is determined. There is no transition to mode. If the response is an acceptance response (Y in step S70), the cooperative play mode is followed (A).

  FIG. 10 is a flowchart for explaining the flow of the transition process from the cooperative play mode to the normal mode according to the present embodiment.

  When shifting from the normal mode to the cooperative play mode (A), the following processing is performed to determine whether or not there is a shift to the normal play mode. The following processing may be performed for each frame, or when there is a series of motion processing or animation processing over a plurality of frames, it may be performed at the breaks.

  It is determined whether or not the third parameter is in a predetermined state. If the third parameter is in the predetermined state (Y in step S110), the special technique usable flag is turned on (step S120).

  Next, control is performed to move the enemy character toward the player character, and a timing gauge is displayed (if the special technique usable flag is on, an icon indicating that the special technique can be used is displayed). A timing input is received (step S130).

  If there is no timing input before the instruction mark reaches the end point position (in the case of N in step S140), it shifts to the normal play mode as a cooperative attack failure (B). When there is a timing input until the indication mark reaches the end point position (in the case of Y in step S140), if the timing input is performed with the first button (in the case of Y in step S142), the timing input It is determined whether or not the position of the instruction mark at that time is within the permitted range. If it is not within the range (N in step S150), the mode shifts to the normal play mode as a cooperative attack failure (B).

  When the position of the instruction mark at the time of timing input is within the permitted range (in the case of Y in step S150), a process for damaging the enemy character is performed, and the player character knocks and knocks the enemy character. Control is performed to generate an image in which an ally character strikes the enemy character (step S160).

  If there is a timing input until the indication mark reaches the end point position (in the case of Y in step S140), and if the timing input is performed with the second button (in the case of Y in step S144), It is determined whether or not the special technique usable flag is on. If the flag is not on (N in step S170), the normal play mode is entered as a cooperative attack failure (B).

  Here, the end point position is a position indicating the end point of the determination section when the presence / absence of timing input is determined using an instruction mark that moves in a predetermined section. If there is no timing input before the moving instruction mark reaches the end point position, it is determined that there is no timing input. For example, the end positions of the permission ranges 246 and 246 ′ shown in FIGS. 5A and 5B (end positions that are farther from the movement start point of the instruction mark and indicate the end of the permission range) 249 and 249 ′. May be the end point position.

  If the special technique usable flag is ON (Y in Step S170), it is determined whether or not the position of the instruction mark at the time of timing input is within the permitted range. In the case of N in S180), it shifts to the normal play mode as a cooperative attack failure (B).

  If the special technique usable flag is on (Y in step S170) and the position of the instruction mark at the time of timing input is within the permitted range (Y in step S180), the special technique process is performed (step S190). ).

  Then, it is determined whether or not the first parameter of the enemy character is a value that means annihilation, and if it is a value that means annihilation (Y in step S200), the process ends, and if the value is not a value that means annihilation ( In the case of Y in step S200), the process returns to step S110 to perform the cooperative play mode process.

  FIG. 11 is a flowchart for explaining the flow of processing for interlocking the instruction mark of the timing gauge and the enemy character according to the present embodiment.

  In the cooperative play mode, the following processing is performed and display control of the indication mark of the timing gauge is performed. The following processing may be performed for each frame, or when there is a series of motion processing or animation processing over a plurality of frames, it may be performed at the breaks.

  The position coordinates of the player character in the virtual space and the position map of the enemy character are acquired, and the distance between the player character and the enemy character is calculated (step S310).

  Based on the calculated distance and the reference distance, the position of the indication mark on the timing gauge is calculated (step S320). Here, the reference distance is K in FIGS. 12A and 12B, for example. At time tn, display control may be performed such that the instruction mark 242 is arranged at a point m-tn such that K: Ln = k: ln.

  Based on the calculated position of the instruction mark, display control for displaying a timing gauge is performed (step S330).

  The present invention is not limited to that described in the above embodiment, and various modifications can be made. For example, terms cited as broad or synonymous terms in the description in the specification or drawings can be replaced with broad or synonymous terms in other descriptions in the specification or drawings.

  The present invention can also be applied to various game systems such as a business game system, a home game system, a portable game system, and a system board for generating a game image.

  Further, in the above-described embodiment, an example in which the teammate character 230 instantaneously moves near the enemy character 220 when the cooperative play mode is started and the enemy character 220 reciprocates between the player character 210 and the teammate character 230 will be described. However, the teammate character may be prevented from moving near the enemy character. For example, when a cooperative attack is performed with a friendly character capable of a remote attack such as magic, the friendly character may perform a remote attack from an arbitrary position and move the enemy character that the player character flew away toward the player character. Good. In this case, the enemy character may reciprocate between the player character and a given reference point in the game space. Then, an effect object based on an action such as a remote attack of a teammate character may be displayed near the reference point.

  Further, in the above embodiment, an example has been described in which the enemy character 220 is damaged each time the player character 210 or the teammate character 230 attacks during the cooperative play mode. However, the player character and the teammate character attack each time. The enemy character may be damaged when it is performed (when the enemy character makes a round trip). Alternatively, the enemy character may be damaged when the cooperative play mode ends.
